HUBBLE SPACE TELESCOPE
DAILY REPORT #2676
PERIOD COVERED: 0000Z (UTC) 07/31/00 - 0000Z (UTC) 08/01/00
Daily Status Report as of 214/0000Z
1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:
1.1 Completed STIS/CCD 8412 (STIS CCD Imaging Flats C8)
The Space Telescope Imaging Spectrograph (CCD) was used to
investigate the flat-field stability of the unit over a monthly period. A
bias calibration observation was also taken. The observations were
executed as scheduled, and no anomalies were noted.
1.2 Complete WF/PC-2 8331 (Probing the Dark Side of Galaxy Formation:
HST Imaging of the ISO Ultradeep Survey)
The WF/PC-2 was used to observe the Hubble Deep Field (HDF) which
gave astronomers an unprecedented view of the optical and rest--frame--UV
side of galaxy formation. However,
new data from ISO and COBE confirms the suspicion that the optical/UV does
not tell the whole story. ISO observations have also demonstrated that
this is true even in the HDF. These show the presence of ~25 galaxies
brighter than ~200MuJy at 15Mum. The observations were completed with no
reported anomalies.
1.3 Completed Two Sets of STIS/CCD 8437 (Dark Monitor-Part 2 C8)
The Space Telescope Imaging Spectrograph (CCD) was used to monitor
the darks. The proposal completed nominally.
1.4 Completed Four Sets of STIS/CCD 8808 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation III)
The Space Telescope Imaging Spectrograph (CCD) was used to make
non-scripted, parallel observations as part of a POMS test proposal. The
observations completed with no anomalous activity.
1.5 Completed STIS/CCD 8439 (Bias Monitor-Part 2 C8)
The Space Telescope Imaging Spectrograph (CCD) was used to monitor
the bias in the 1x1, 1x2, 2x1, and 2x2 bin settings at gain=1, and 1x1 at
gain = 4, to build up high-S/N superbiases and track the evolution of hot
columns. The proposal completed with no reported problems.
1.6 Completed Three Sets of WF/PC-2 8826 (Cycle 9 Supplemental Darks pt 1)
The WF/PC-2 was used to perform a T dark calibration program that
obtains three dark frames every day in order to provide data for monitoring
and characterizing the evolution of hot pixels. There were no reported
anomalies.
1.7 Completed STIS/CCD/MA1/MA2 8297 (The Physical State of the
Starburst Outflow in NGC1705)
The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was
used to perform echelle M mode spectroscopy from 1200 Angstrom to 3000
Angstrom of the nearby starburst galaxy NGC1705 to probe the physical
conditions in the starburst- driven galactic superwind. The proposal
completed with no reported problems.
1.8 Completed Two Sets of WF/PC-2 8805 (POMS Test Proposal: WFII
Parallel Archive Proposal Continuation)
The WF/PC-2 was used to perform a generic target version of the
WFPC2 Archival Pure Parallel program. The program will be used to take
parallel images of random areas of the sky, following the recommendations
of the Parallels Working. The proposal completed with no reported problems.
1.9 Completed WF/PC-2 8812 (Cycle 9 Internal Monitor)
The WF/PC-2 was used to obtain routine internal monitors for WFPC2
in order to monitor the health of the cameras. A variety of internal
exposures are obtained in order to provide a monitor of the integrity of
the CCD camera electronics in both bays {gain 7 and gain 15}, a test for
quantum efficiency in the CCDs, and a monitor for possible buildup of
contaminants on the CCD windows. There were no reported problems
1.10 Completed WF/PC-2 8811 (Cycle 9 Standard Darks)
The WF/PC-2 was used to obtain dark frames every week in order to
provide data for the ongoing calibration of the CCD dark current rate, and
to monitor and characterize the evolution of hot pixels. Over an extended
period these data will also provide a monitor of radiation damage to the
CCDs. The proposal completed with no reported problems.
1.11 Completed WF/PC-2 8193 (Comparing the Hosts of High-Z Radio-Quiet
Quasars to Lyman Break Galaxies)
The WF/PC-2 was used to try to determine the underlying causes of
the rapid cosmological evolution of the quasar population that is a mystery
around which is woven many different strands of contemporary
cosmology. The proposal completed nominally.
1.12 Completed STIS/CCD 8870 (POMS Test Proposal: STIS Non-Scripted
Parallel Proposal Continuation IV)
The Space Telescope Imaging Spectrograph (CCD) was used to make
non-scripted, parallel observations as part of a POMS test proposal. The
observations completed with no anomalous activity.
1.13 Completed STIS/CCD 8236 (Black Holes and Gas Disks in a Complete
Sample of Radio-Loud Ellipticals - II: Kinematics)
The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of the radio-loud elliptical galaxy NGC-7626. From these
observations we will measure the black hole masses, determine the nature,
kinematics, and structure of the central gas disks and obtain a modeled
upper limit to their mass accretion rates. A wavelength calibration image
was also taken. The observations were completed as planned, and no
problems were reported.
1.14 Completed WF/PC-2 8162 (Identifying The Hidden Phases Of Galaxy
Evolution)
The WF/PC-2 was used to perform deep surveys in the sub-mm waveband
that are revealing a population of very luminous dusty galaxies at high
redshifts, which are {a} as a population, producing stars at a rate as
large or larger than the optically selected galaxy population at high
redshifts and thus presumably producing a substantial fraction of all stars
that have ever been produced; and {b} doing so, individually, in systems
with bolometric luminosities (i.e. star-formation rates} that are very much
larger than typically seen in the optically-selected population). The
observations completed with no anomalous activity.
1.15 Completed STIS/CCD 8413 (STIS Yearly CCD Wavelength Monitor)
The Space Telescope Imaging Spectrograph (CCD) was used to execute
the yearly CCD wavelength monitoring program. This is a continuation of
program #7650 that was executed during in Cycle-7. The observations were
completed as planned, and no problems were reported.
1.16 Completed WF/PC-2 8645 (A Survey of Mid-UV Morphology of Nearby
Galaxies: Galaxy Structure and Faint Galaxy)
The WF/PC-2 was used to investigate the relation between star
formation and the global physical characteristics of galaxies to interpret
the morphologies of distant galaxies in terms of their evolutionary
status. The observations completed nominally.
